Another US School shooting ...ZZZZZZZZ, page-41

The parents were called to a school counsellor meeting hours before the shooting & told to get their son to therapy within 48hrs.

Instead the parents left their son at school, apparently unaware that he had the gun in his backpack.

"James and Jennifer left the high school without their son. He was returned to the classroom," prosecutor Karen McDonald recounted.

Jennifer Crumbley texted her son: "Ethan, don't do it," but by then he had already started shooting."
